Just a general question regarding the H10/H11. Doesn anyone know if they should be able to fit in the same housing (not taking about harness fitment). What I mean is if the H10 fit in a specific housing, is there any reason why the H11 would not fit in the same housing? I have a fog light set that comes with an H10 bulb, but I currently have H11 HIDs, so If they cross fit, I can just use my current H11 setup in the same housing that the current H10s are in.
